I can't tell you that it does not have a problem for sure. but it does show that you are accessesing the autodiscover site. However if you had a cert error and maybe multiple prompts or event a single prompt you may still have issues depending on how you
are configured. But the autodiscover virtual directory appears to be working as expected.

Yasser you are posting on 2 seperate threads. so if you are recieving the Log on that is good. can you tell me more about your environement is it a single CAS server, exposed to the internet? or is it behind a proxy, or behind a firewall? do you have more
than 1 cas?

So it depends on how your DNS is configured if you run split DNS which now a days you pretty much have to. then you do not have to have any of the internal names on the Certificate.

Split DNS means you have an internal DNS zone for your external Name space. and you put in all of your internal IP's and external IP's and names for that space in manually to be sure clients can go to the right place.

خwhen i configure outlook from outside it ask me for user and pass then i write the user and pass and it is accepted and the server name be underline also the user name be underline but the problem is the user name changed as i explain for aprevious replies

when am trying to open the outlook

the problem with the a proxy server security certificate the security certificate not from trusted Ca

This means that you do not have the Root cert from your Certificate authority in your trusted root store. I know you said you put the Cert in the store. but was it the cert you issued to Exchange? You need to be sure you have the proper root certificate
on you machine.

Easiest way is go to your CA web page and I believe you should see download Root certificate. Download it. then open an MMC by going to the run command and type MMC then add in the certificate store. when it prompts say local computer then find the trusted
root certificate folder. then right click and say import find the file you downloaded from your CA and import it in.

You may have to create the registry key. but what this is doing is telling outlook not to use the root domain. once you test it if it works. Then the real fix is making what ever website is responsible for answering on
https://domain.com not answer on that address. hope that helps.

Click Start, click Run, and then type regedit.

2.Navigate to the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\AutoDiscover

3.Set the following values for the Value Names listed below:
"ExcludeHttpsRootDomain"=dword:1
